ARMORED TIRE.

To all whom 'it may concern:

Be it known` that I, lViLLIAM H. EYNON, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Armored Tires, of which the following is a specification.

My invention relates to improvements in armoredv tires, and more particularly, to improvements in pneumatic tires of either the single-tube or double-tube type.

The primary object of the invention is to provide a generally-improved non-puncturable tire of this class of simple, cheap, and efficient construction adapted to provide increased durability and reduce the cost of maintenance of such tires.

Practicalv experience in the use of pneumatic tires has demonstrated that the maximum destruction or wear and tear of the tire is not due to punctures or excessive wear upon the tread of the tire, but that in the class of tires which use a separate cover, such as the Dunlop or clenchertires, or in the cylindrical tire the greatest deterioration is due to the constant changes in the material of which the tires are made by the flexure of the tire on its sides between the tread of the tire'and its bearing on the rim of the wheel. In the covers or casings of the Dunlop and clencher type of tires this flexure is very pronounced and weakens the sides of the cover very rapidly, and this flexure causes the canvas to break in successive layersk from the outside inwardly circmnferentially under the tread of the tire. This deterioration of the fabric bod isalso augmented by the friction .of the body of air under hi h pressure within the tireas it is displace bythe revolution ofthe wheel due to the high degree of heat generated 'in the tire by the moving body of a1r.

The pur ose of this invention is to protecz an reinforceithe atter for the purpose o preventing punctures and blow-outs, and at the same time not affecte by lexure or friction and is capable of sustaining a high degree of pressure applied to the air used to inflate the tire.

' With the above mentioned ends in-view,

l the invention consists in the novel construcspeciacatio of Letters Patent.

Application filed July 22, 1909.

providing a tire casing which is.

Patented J ulfy 12, 1910. Serial No. 508,940.

its embodiments in the accompanying drawv metallic armor fabric in the form of closemesh woven wire. Fig. 3, a similar view of the same in the form of ymail-armor consistving of interlinked rings.

imilar numerals of reference designate like parts throughout all the figures of the drawings.

The present embodiment of the invention shows a tire of the double-tube type consisting of a sheath or tire-casing l, and an inner'inflatable tube-2. The sheath or tirecasing may be reinforced in any suitable and convenient manner by means of a vegetable or canvas fabric body comprising layers of fabric 3, suitably disposed and incorporated and preferably extending into the heel portions la, of the tire casing as shown.

The tread portion l", of the tire casing ma be of any suitable and convenient form and7 may be provided with a breaker-strip 4, consisting of one or more strips of fabric as desired.

The breaker-strip, as its name implies, affords a limited rotection to the fabric body 3, at the trea portion of the tire.

As heretofore pointed out, the deterioration of the tire casing is greatest at the sides where subjected to greatest flexure, and asa consequence what are known as blowouts frequently occur in these portions of the tire. l

As a means for efl'ectually reinforcing the outer tire casing or sheath and rotecting the fabric body 3, thereof, a meta lic armor fabric is embedded and vulcanized therein, said armor fabric comprising a main body or tread portion 5, terminatmg at its sides in a series of anchor strips 6, arranged at suitable intervals and extending transversely in the sides 1c, of the tire casing. The main body portion 5, of the armor fabric extends throughout the tread portion of the sheath or tire casing andthe transversely disposed anchor strips 6, preferably extend into the heelfportions l, terminating in hooked portions'a, effectually reinforcing the heel portions 1, of the tire casing and strengthening the sides of the tire casing l, for the purpose. of preventing blow-outs as above referred to.

The metallic fabric preferably comprises flexible mail-armor as indicated in Fig. 3, of

the drawings, but may be composed of closemesh woven Wire fabric as indicated in Figs. 1, and 2, of the drawings.

If the breaker-strip 4, is retained as .a feature of construction in the tire casing, it is preferably disposed just outside of the maln body portion 5, of the armor fabric, and the anchor strips 6, may be of any suitable dimensions and disposed at such intervals as may be found most eHective for affording the requisite elasticity and reinforcement in the sides 1c, of the tire casing.

From the foregoing description, taken in connection with the accompanying drawings, the o ration and advantages of my invention wi l be readily understood.

Having thus described an embodiment of my invention, what I claim and desire to secure by Letters Patent is,- v

l. An armored-tire, comprising a sheath having embedded therein a flexible metallic armor consisting of a main body portion exV tending throughout the tread portion of said sheath and provided with. portions of substantial Width and separate from each other disposed in the sides of said sheath.

2. An armored-tire, comprising a sheath, and a flexible metallic armor embedded therein comprising a tread portion provided with a plurality of transversely disposed portions of substantial width and separate from each other terminating in the heel p0rtions of said sheath.

In testimony whereof I have affixed my signature, in presence of two witnesses.
